Dredged Material Management

Comprehensive Dredged Material Management Support

Several hundred million cubic yards of sediment are dredged from U.S. ports and waterways annually to maintain navigational channels and facilitate commerce, national security and recreation.

The regulations for dredged material disposal in U.S. waterways and oceans are complex, and are managed jointly by the U.S. Army Corps of Engineers (USACE) and the Environmental Protection agency (EPA).  The USACE and EPA, in conjunction with a number of states, have developed guidance documents to support decision making associated with dredged material management.  To support this decision making process, TestAmerica provides chemical and physical environmental testing services to assist in the evaluation of the potential environmental impacts of dredged material discharges.  

Potential dredging sites vary in their size and complexity. Dredged material evaluations often involve more than one environmental matrix, which can include sediment, surface water, elutriates, leachates, and tissues.  TestAmerica has extensive experience providing chemical and physical testing services in support of dredged material evaluations projects nationwide. These projects have been executed with oversight from various EPA Regions, USACE Districts, and state agencies. Guided by industry leading expertise and unmatched laboratory capacity, TestAmerica’s goal is to generate chemical and physical testing data to meet project specific objectives, thereby facilitating appropriate dredged material evaluation decisions.

How Can TestAmerica Help You?

TestAmerica’s 20 years of dredged material experience has consistently demonstrated that a critical factor for project success is a dedication to pre-project planning, including Quality Assurance Project Plan (QAPP) review, and an evaluation of targeted reporting limits for each project. TestAmerica has the experience and resources to support each project team’s goals, achieving mutual success in the execution of dredged material evaluation testing programs.

Chemical Testing

TestAmerica follows EPA methods and USACE procedures to evaluate dredged material samples for various contaminants of concern. Our chemical testing program supports matricies such as sediments, site water, elutriates, leachates and tissues.

Physical Testing

Physical, or geotechnical, testing is performed as a fundamental part of the dredged material evaluation process to support the characterization of sediment samples.  Since the late 1990s, TestAmerica has supported geotechnical testing for sediment projects. Our support includes a variety of tests including; grain size, atterburg limits, bulk density, specific gravity, water content, permeability of granular soils, classification of soils, moisture, ash, organic matter of soil, and others.

Elutriate, Leachate Generation and Column Settling Tests

TestAmerica supports all industry recommended elutriate and leachate generation procedures, as well as column settling tests required under the Ocean Testing Manual, Inland Testing Manual, Upland Testing Manual and various state guidance documents.
